262 | |
263 | =head1 SYNOPSIS |
264 | |
265 | =head1 DESCRIPTION |
266 | |
046ad905 |
267 | This class represents the connection to an RDBMS via L<DBI>. See |
268 | L<DBIx::Class::Storage> for general information. This pod only |
269 | documents DBI-specific methods and behaviors. |

285 | =head2 connect_info |
286 | |
bb4f246d |
287 | The arguments of C<connect_info> are always a single array reference. |
1b45b01e |
288 | |
bb4f246d |
289 | This is normally accessed via L<DBIx::Class::Schema/connection>, which |
290 | encapsulates its argument list in an arrayref before calling |
291 | C<connect_info> here. |
1b45b01e |
292 | |
bb4f246d |
293 | The arrayref can either contain the same set of arguments one would |
294 | normally pass to L<DBI/connect>, or a lone code reference which returns |
295 | a connected database handle. |
d7c4c15c |
296 | |
2cc3a7be |
297 | In either case, if the final argument in your connect_info happens |
298 | to be a hashref, C<connect_info> will look there for several |
299 | connection-specific options: |
300 | |
301 | =over 4 |
302 | |
303 | =item on_connect_do |
304 | |
305 | This can be set to an arrayref of literal sql statements, which will |
306 | be executed immediately after making the connection to the database |
307 | every time we [re-]connect. |
308 | |
309 | =item limit_dialect |
310 | |
311 | Sets the limit dialect. This is useful for JDBC-bridge among others |
312 | where the remote SQL-dialect cannot be determined by the name of the |
313 | driver alone. |
314 | |
315 | =item quote_char |
d7c4c15c |
316 | |
2cc3a7be |
317 | Specifies what characters to use to quote table and column names. If |
318 | you use this you will want to specify L<name_sep> as well. |
319 | |
320 | quote_char expects either a single character, in which case is it is placed |
321 | on either side of the table/column, or an arrayref of length 2 in which case the |
322 | table/column name is placed between the elements. |
323 | |
324 | For example under MySQL you'd use C<quote_char =E<gt> '`'>, and user SQL Server you'd |
325 | use C<quote_char =E<gt> [qw/[ ]/]>. |
326 | |
327 | =item name_sep |
328 | |
329 | This only needs to be used in conjunction with L<quote_char>, and is used to |
330 | specify the charecter that seperates elements (schemas, tables, columns) from |
331 | each other. In most cases this is simply a C<.>. |
332 | |
333 | =back |
334 | |
335 | These options can be mixed in with your other L<DBI> connection attributes, |
336 | or placed in a seperate hashref after all other normal L<DBI> connection |
337 | arguments. |
338 | |
339 | Every time C<connect_info> is invoked, any previous settings for |
340 | these options will be cleared before setting the new ones, regardless of |
341 | whether any options are specified in the new C<connect_info>. |
342 | |
f5de3933 |
343 | Important note: DBIC expects the returned database handle provided by |
344 | a subref argument to have RaiseError set on it. If it doesn't, things |
345 | might not work very well, YMMV. If you don't use a subref, DBIC will |
346 | force this setting for you anyways. Setting HandleError to anything |
347 | other than simple exception object wrapper might cause problems too. |
348 | |
